DSP Speakers setup and room correction

How to use SPL meter to do speakers setup? How to use calibrated mic to do room correction with Roon? I am using Mac Pro which installed Roon core, Synology DS 218+ NAS and MSB Discrete media player. Is there any video or instruction can share with us?

Dear All

Thanks you very much for your kind reply!

I can install Roon core either on synology NAS with SSD or Mac Pro. Which is the best way?
